Circuit Description
WARNING: This page is about a different car, the 2003 Lexus ES 300 and 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The power door lock system uses a large-scale body multiplex communication system. First, confirm the communication function and check that there is no abnormality in the communication system. See POWER DOOR LOCK SYSTEM under TROUBLE SHOOTING.
When the ignition switch is in ON position, the body ECU monitors the signal via the power door lock motor.
